Yesterday, I was using the Google navigation on 3G network with the phone connected to a 500mA car charger. After 1hr, the battery dropped 20%...Anyone knows if a 1000mA car is enough??
Tonight, I was watching a Youtube HD video on 4G network (2/3 bars on 4G) with the phone connected to a 1000mA USB wall charger. After 10min, the battery dropped 2%...Well, even 1000mA cannot compensate the consumption of the battery.
The power consumption of this phone is ridiculous. Something must be wrong with the system/circuit design.
NOTE: I'm not complaining the battery but the power consumption of this phone. The charging cannot compensate the usage of the power. Think about a laptop. It's even more powerful, but you can use it freely without any concern about the battery as long as you plug it in an ac adapter. Why can't Epic 4G do this?
man i been seeing the same problems i was listen to the sprint radio while hooked up to the charge and would see it stay at the same percent for about a hr before it went up 1%. this battery issues is making me hate the phone right now and i cant find any rapid charge programs or settings for this yet. cant wait for some custom rom to come out that hopes to fix some of these issues
yup 4g is a battery hog which is why people are complaining about battery life,I suggest you turn it off, it's just not worth it IMO, which too bad cause we're paying extra afterall.

I saw a post this morning. The 3G even consumes more battery on Epic 4G during browsing. so we can expect even worse under 3G.
I'm on my third Epic and they have all had battery drain issues. Battery manufacture dates ranged from July to mid August. Right now actually, I'm streaming some radio over 3g and have an AIM client running in the background and the batter is slowly draining while plugged into the charger included in the box.
I have tried a factory reset just to be sure any apps I installed weren't affecting anything and still no dice. Even with running navigation in the car while plugged into a usb charger the battery will drain about 1% every 5 minutes or so. I'm probably returning the phone for good in a few days
This is with 4G disabled, using SwitchPro widget to enable 3G. I also have background updates disabled(under accounts/sync), I manually do them periodically.

That shoul be more than enough. I use a Motorola-branded 850mA microUSB car charger (quite cheap on Amazon). On a recent day-long driving trip, it was sufficient to maintain the battery level while streaming audio over 3G and simultaneously running GPS tracking. I don't think a 500mA unit would have handled the load, however.
I'm really starting to think this phone is an epic fail. I get from 1.5 hours to 2 hours of use from a full charge! Thats with everything off, 4G, wifi, bluetooth, GPS. The sprint store manager wouldn't exchange my phone because he said their is nothing wrong with it. If it takes 6 hours to charge and then I get 2 hours of use, this phone is worthless to me!

Yeah that doesn't sound right. I think most people would have a hard time making it last only 2 hours. Maybe gaming while running WiFi tether.
Keep in mind with CDMA, the lower the signal to the tower, the more power it takes to keep the connection active. For GSM this is less of an issue. How is the signal where you live?
An interesting side note. I plugged in my charger for my Bluetooth which is only 180ma and it went from 70% to "Fully Charged" in 10 seconds. When I unplugged the charger it went back to 70%. It really didn't like that low power feed.
Sorry if it came out orange. I used screenshot the app and that's what i got. Anywho, its a perfect combo what I've done. See the up time, nearly 15 hours up time. I only lost 35% of life during the time too as you can see how full the batt is.
Remedies: Autokiller set to extreme. ATK: Set to aggressive, with auto kill set to when screen is off. Interval every hour. Cachemate: all settings lit up, so it clears about 12-14 MB every hour or 1-2 every manual clear. Set CPU: Conservative 1000/100 with set to boot. Notice, set CPU resets itself every reboot for now, just make sure your good.
Then you should be good as I have for TWO days on one charge nearly 24 hrs ago.

I would love to see more info/screenshots on this. The one SS you included somehow ended up thumbnail sized only. 2 days is nuts, anything over 24h would be.
hey guys
I've been really happy with the battery life on my epic - I get about 12-14 hours with on-off use, 4G off. My battery is sitting at about 35% after playing a bunch of games for about 3 hours in between classes and it has been running off battery for about 8 hours, browsing the web, sending texts and downloading apps on both 3g and wifi.
I'm using Advanced Task Killer and its set to kill aggressively every half hour - it kills all apps except Juice Defender, itself and LauncherPro.
I'm running LauncherPro - if that matters - doubtful, but I didn't like touchwiz. And I'm running JuiceDefender on default settings. Basically it kills the 3G radio when screen is off unless its transferring > then 15kbs of data. The normal radio remains on for calls/texts.

What is the EVO fix? I'd love to try some extra tips.
My two cents - a typical day puts me at home and at work for the majority of the day and night, which both have wi-fi. I've turned off "look for open networks", "never allow wi-fi to sleep" and I leave wi-fi on. After a full night of charge I took the phone off of the charger at 11am on Saturnday and it finally turned off Sunday at 8pm - 33 hours is pretty darn good, almost two days. However yesterday I took the phone off the charger after leaving work at 6:30pm (so no wi-fi, just 3G) and in just an hour with watching a 15 minute long normal quality YouTube video, a few texts and a short phone call I was down TWENTY PERCENT. What the heck.
Over wi-fi, like I said, I'm good - great battery life since I'm not waking up the 3G radio to do anything. But when I get out of those wi-fi areas that's when my battery starts to drop. Anandtech is getting similar results with awful 3G battery:
http://www.anandtech.com/show/3891/samsung-epic-4g-review-the-fastest-android-phone/8
Something is wrong with the 3G radio, and I hope Sprint & Samsung seriously do something about it.
You guys are all failing to look at "Cell standby" details.
Time without signal on this phone - no matter WHAT coverage area you're in - is ALWAYS > 50%. This is bull**** and a Samsung software issue. Take a look for yourself.

I never had a problem with but I've been reading many having a problem with "Cel Standby" going out of control. Mine it at 17%. Highest I have saw it was in the upper 30's range after a full day (14hr)
Just an update on my usage from Pg.1:

I am not seeing this issue. Never seen it above 3%. Besides most of the battery is going to the screen it seems. I am actually wondering if it reporting the usage correctly. If the screen was really take that much of the power, it should be lasting a lot longer.
People getting great battery life are reporting they are using task killers and data connection blockers. That isn't even where they majority of the power goes. The system tells us it is going to the screen. Not the tasks or data connections. It seems counter-intuitive.

Turn airplane mode on then off. (settings -> Wireless & Networks)
This will solve the problem until the next time you reboot. You must do this after every reboot.
I'm working on a more scientific breakdown of power consumption. But here are some brief findings.
The highest power consumer is the display. Even on the lowest brightness setting it consumes more power than a normal LCD (I'm comparing it to my Evo). If the display is only showing a black background it is lower power, but then again if all it is showing is noting, it may as well not be on at all. If you actually want to display something on the screen, it consumes power like it's going out of style. So much for Super AMOLED being a power saver (total and completely false.)
The next highest power consumer is the 3G radio. Under similar circumstances (similar signal strength) the 3G radio is consuming more power than the 4G and Wifi radios combined. Wifi seems to consume the least, followed by 4G then 3G. This is crazy and if not fixed might be unacceptable.
Next is background apps, most specifically anything that uses the network (email syncing, social networking and location reporting services like latitude) being the worst. The sync settings on the Epic are not as robust as the Evo and I've struggled to gain control of gmail without just setting it to manual only. Do not use latitude and although some will speak out against task killers, having one to keep "maps" at bay is worth it alone.
Then there are more obvious things like live wallpaper. Or specifically anything using the CPU / GPU and GPS.
More to come, but right now, something must be done about the 3G radio and GPS or this phone could live up to the moniker of Epic fail. I really hope Sprint and Samsung are doing something because otherwise if the phone worked as it could, it would be awesome.
I have epic 4g now for a week. Its still not activated, just sits at home connected to wifi - while I use touch pro2, awaiting sero plus on oct 1st.
There is push sync with hotmail and google. I get home and play almost constantly with the phone from 5 to 11pm - testing new apps/games, reading twitter etc - before I get low battery warning.
My biggest surprise was that the SCREEN (supposedly high efficency AMOLED) is draining more than 40% of the battery! Not the wifi, not the cpu or whatever else is inside. This is with default power managment settings.
What numbers do you guys get in the end of the day? What are you using - 3g,4g,wifi,gps,apps?
Sent from my SPH-D700 using XDA App
Sometimes mine goes as high as 72%, and that's the screen alone, and i have the brightness down all the way to zero (and even at zero it's still plenty viewable).
Definitely the screen is the biggest battery drainer. I've NEVER seen anything higher usage than the Display. Its usually in the 60-80% of battery usage.
And I keep the power to the lowest setting on a daily basis.
The screen is always the biggest offender. Usually in the 70%+ range with brightness all he way down. The samoled talk is just marketing bs. Maybe better performance when the screen is black. Unfortunately all black backgrounds happen to be the minority on websites, applications etc.
Display used to be the main offender on my phone (60-70%) but since I upgraded to DI07, Cell Standby is crushing my battery. The airplane toggle doesn't do ****, had to buy a cable so I can plug it in at work just so at the end of an 8hr day I have more than 30% battery left even with JuiceDefender running. Getting pretty frustrated.

I have this exact same issue. Cell standby is killing my battery. Right now I have 18% time without signal... it has been as high as 25% before. I never had this issue before DI07.
Cell Standby is 41%, with Display at 32%, time without signal is a whopping 50%, and I get near-full to full bars at work and about 2-3 at home.
my cell standby was over 50% after the update. I went in and changed my call setting>System select and chose "sprint only" which will not allow the phone to roam, but it got rid of this battery drain. I have a lot more battery now. But i will have to turn it back whenever i loose service. There's got to be a better way to avoid this thing always looking for the GSM towers when it's a SPRINT PHONE and should for CDMA unless there's no signal. I don't understand how they allow such a dumb issue to haunt tihs phone.
My current numbers:
Cell Standby: 34%
Phone idle: 25%
Display: 17%
Android System: 10%
Email: 5%
Maps: 3%
Dialer: 2%
Wi-fi: 2%
Android OS: 2%
Cell standby has gone up for me since the update, but my last charge was actually the first time I saw any significant "time without signal", and I think that was because I had 4G turned on all day. I have it turned off now and that number is back to 0%.
I'm learning some tricks to keep the battery charged on this thing. Yesterday I managed to go all day from waking up to going to sleep without charging (around 18 hours, though I rebooted at one point so I'm not sure the actual total) and I still had about 1/5 of my battery gauge left.
I've found wi-fi makes a HUGE difference. I have wi-fi both at home and at work, and that's probably 80% of an average day for me. Wi-fi drains the battery *much* less than 3G.
I have my screen turned down not to 0, but probably 2 ticks over that. I use the notification bar swipe to turn it up or down, so I don't know exactly, I just set it to as dim as I'm comfortable with in any situation. Power mode and auto-brightness are turned off.
I switched my background from the default to one that's very dark. I'm convinced that makes a big difference.
I do use a task killer, but I leave my email running, along with whatever else seems like it should be kept running.
Obviously when you look at percentages, there's always going to be *something* at the top of the list, so it's pointless to constantly try to knock whatever's #1 down to the bottom. Different people use their phones differently, so if someone else has their display at the top, it just means they're looking at it a lot and maybe have it too bright. But no matter what you do, something's always going to have a higher percentage than anything else.

How are you able to control the brightness with the notification swipe? I've made it brighter but not dimmer.
Sent from my SPH-D700
So for all the people that have their phone on the lowest brightness, but get a Display usage >50%...are you using your phone that much?
Because I have my display on auto, and my Display usage is a 32%, and that is still enough for it to be #1 on my battery use list.
First, let me get the immature response out of the way: "What sucks my battery? Your MOM!"
Now that that's out of my system, my battery drain is generally caused by the same things as everyone else: screen and TWS. Although I mitigate TWS by using the airplane mode trick which seems to still work for me.

I dunno, I just do. The way the thing works is a little tricky, it seems like it's absolute rather than relative, meaning if your display is already on the dim side, you need to start with your finger way over to the left to take it down the last few ticks. There's only so dim you can make it - the lowest brightness setting would look like a 4 or 5 year old phone at its brightest. That's true regardless of how you dim it. So you may just have it pretty dim and because of the way the notification bar thing works, when you put your finger in the middle, you're making it brighter without meaning to. But if you slide all the way to the left, it'll be as dim as you can make it.

(I'll preface this by saying that I am well aware there have been a million threads about this, I'm sure, and I'm even more sure that there will be a million more. And I have searched, and searched, and searched some more, and I still feel the need to post this question. Flame me if you want. I'll use the flames to heat up some tea, or something.)
I bought my phone last Thursday, it got lit with service Friday. I went over the weekend and into Sunday with stock ROM/kernel, and decided to mix things up by rooting my phone and using the MixUp kernel to see if I could get better battery life.. and it didn't work too well. I mean, life went up a bit, but not noticeably so (maybe twenty or thirty minutes?)
After that, I flashed Syndicate, which had Xtreme Kernel. I calibrated the battery as instructed inside of Clockwork and went with it for Tuesday.. took it off the charger at 8:00 and it died around 4:00. Kept the same kernel and flashed Epic Experience and the attached JuicePlotter shot is where I am at right now.
My usage today has been light browsing and that's basically it. I've got the processor underclocked to 600 with SetCPU, and JuiceDefender and Superpower have been preventing any data from going on when my screen is off, and for the last two hours I've been listening to MP3s using the in-built music player.
This makes me cry considering there are people on here saying they're able to get much more life out of their battery, even with BT and WiFi etc. I'm aware that each phone is different and all that, but still.
All that said, is there a problem with my phone/battery, is this par for the course with the Epic, or should I just stop whining?
Thanks in advance for any help/insight.
A couple of things...get a task killer app so that you can kill the drm process which eats up a ton of battery, calibraing your battery takes 2 or 3 times going from full charge to zero and also, since its a new phone it takes charging to full and letting it get down to complete zero a few times before you will see better battery life no matter what else you do
Edit: oh and also definitely do the airplane mode toggle as well

Also, for each new Kernel you flash, you have to calibrate the battery.
Charge it to full, boot off, boot up in Clockwork, go to Advanced and Clear Battery stats. Reboot the phone, use it until it runs dead and shuts off, than plug it back in and charge it to full with the phone on.
Every time you flash a new kernel, you have to do that process so the battery calibrates to that certain kernel.
Also, try Baked Snack, it gets the best battery life for 2.1 ROMs.

Download Bakedsnack1.6 and Step 2.
Make a backup.
Wipe data/cache
Install 1.6
Boot the phone up
Reboot into clockwork
Install Step 2
Boot the phone up.
I have to have a car charger if I go anywhere. This phone dies so fast with normal usage. Do anything crazy like turn features on, surf the web, or increase brightness, and I am lucky to get 2 hours. I have multiple batteries, both have the same result.

2 Hours..? Whaaaaa? Lol.
When I calibrate my battery, I turn EVERYTHING on, screen brightness all the way up, Pandora running, every widget I can fit on my screens set to update at their quickest setting, screen set to 30min (Though I never let it shut off). Bluetooth, GPS, 4G running (I don't have 4G here, so it just keeps searching, which drains it more than if it was connected). And running the Maps Live wall paper to use GPS.
When I do all that, I can't get it to even die under 4 hours.
Hopefully you were exaggerating with saying 2 hours lol.
Thank you guys for replying!
Sh0wNuF: I killed the DRM service today and used ATK to kill errant processes throughout the day today to no avail. I also used the airplane mode toggle to try to limit my time without a signal.
SemiGamer: Thank you! I did do the clockwork step as I said in my first post, but I will try to install BakedSnack and get back to you guys as to the battery life.
From the looks of that juiceplotter graph, your data is constantly on and destroying your battery. What is the point of having juicedefender if the data is constantly on?
If you set up the phone properly, and there are a MILLION threads on this which state a MILLION times to disable DRM and toggle airplane mode as a mere baseline beginning, you should lose at most 1% an hour when the phone is idle without a data connection and the screen off.
Now it looks like you probably have the data on constantly with emails rolling in, facebook auto updating every 5 minutes, weather checking every half hour and other things that are just destroying your battery life. If you need your phone to do all that nonsense, then you will be crying for the rest of the time you have it.

Thank you for your reply, but as I said in my first post, I was using both JuiceDefender and Superpower to make sure data was off in the background, and as I said in my most recent post, I did disable the OmaDrm service as well as enable/disable Airplane Mode to lower my TWS.

Thats fine, but your data aint off. Look at that graph you posted. Every little blip is either data being accessed or the screen turning on. The line should be smooth if there is no data and no screen on.
So there are two options, either you are constantly using the phone and its the screen killing the battery, or you have juicedefender set up all wrong and its the data killing the battery.
If I remember correctly, any spike below the line is data, either wifi or 3g and any spike above the line is the screen turned on. So from the looks of it your data is literally never turning off and you are checking the phone and turning the screen on and off pretty frequently.
What are your settings in juicedefender?

I have almost identical batter results as you. I do use the phone fairly often to send messages but the screen brightness is all the way down and I use set cpu on the froyo beta leak. I reset battery stats and also (perhaps you could look into this too) checked spare parts for any rogue programs. Does yours say the screen takes up most of your battery even if you barely use it?

I would up the Schedule to less often and turn off the traffic toggle. Also, I wouldn't doubt that your phone is never going to sleep. If you have spare parts check the Battery History. If you listen to music with the phone, the service started by the music player, CorePlayerService, keeps the phone awake constantly for me. I ended up making a simple kill music widget using tasker to fix this issue.
I bought a wildly overpriced Samsung stand/battery charger from Amazon. My wife & I each start the day with a charged Epic and a spare battery. No worries

Used BS 1.6 w/ step2 kernel today. MUCH better battery life but my phone was acting just a bit wacky (locked up and required batt. pull twice or three times)
Not the biggest fan of the aesthetics of the ROM.. but I'll live.

When you say much better battery life exactly how much? My battery dropped 20% today while not being used and Display was still at 60% (I turned the alarm off twice). I'm running the Quantum ROM which could have something to do with it but the battery is horrible for me. I can't get more than 8 hours and that's if i barely use it. I have spare parts and no apps are partially waking it. Just Wifi and sync. No GPS, brightness all the way down. The main thing that bothers me is that display is always #1 even if i don't use the phone at all. Any thoughts?
I've ran both Quantum and Viper Froyo roms and aside from making my phone hot enough to fry eggs, the battery life was not good.
As far as battery life goes, I'll start with the obvious stuff.
1. Turn off GPS, Bluetooth and 4G. 4G is a complete power whore.
2. As for wifi, turn it off unless you are in a bad coverage area for cell data. If you are connect to wifi and set Spare Parts to never let wifi sleep.
3. For DRM there are 3 files you need to remove that will prevent it from running / reinstalling and they are DrmProvider.apk, DrmUA.apk, and SisoDrmProvider.apk.
4. Toggle airplane mode every single time you reboot without fail.
For a true test of whether your phone simply needs to be returned as "defective" you should wipe the device, dont setup a google account and let it run for a day after executing steps 1-4 above. It would be best to an apk for Spare Parts and SDX Stock App Remover on your microSD that could be installed using My Files. If you still have problems take the phone back to sprint (after restoring it to factory of course) and tell them it is defective.

Here's a JuicePlotter graph from today for comparison from my original one yesterday.
I still wonder if it wasn't going to sleep because of PowerAMP and I didn't underclock today like I did yesterday.
There are a few other physical issues with my phone (slider seems a bit loose compared to my other phones: if I swipe with slider closed with a bit more pressure than usual, I can feel the screen move up and down; screen seems to slightly come up a bit when phone's tilted a bit, taps make you feel the screen go back down) that also made me want to consider exchanging it on top of the battery issue but if I'm getting good battery life I don't think I'll mess with what works, unless anything gets worse.
Hi,
I got my second android phone (LG G2 obviously) this christmas, and I haven't had time to properly use it (I don't have a micro SIM yet). I noticed that my battery is going empty pretty fast, although I heard this phone has a amazing battery. My friend got this phone too and he told he's been on one charge for about 36 hours with constant wi-fi connection, app downloading, playing games etc. so I figured something's off. I charged the device before going to bed and when I woke up (10 hrs later) battery was on 85% (only 2 MINUTES of screen time!!!!) and I had no apps running on the backround, no nothing. So now I'm thinking is there some easy fix for this or should I return it and get a replacement? Also something weird I noticed yesterday was that even though I don't have a SIM card yet, but 16% of the battery was used by the phone application. I did some screenshots of battery usage today and yesterday too if anyone's interested.
There are literally dozens of similar threads... suggest you start searching.
And I literally have gone through 90% of them so I decided to start a new thead. Do you (or someone) think that a factory reset could help? And the next question might sound stupid, but if I do a factory reset then does the warranty remain? Better safe than sorry I guess
I just played 4 minuts of hill climb racing and lost 3% of my battery, this is not normal. Does anyone even have a solution for this? All I see on other threads is questions and questions, but I don't see anyone saying "That worked and my battery life is normal now"
It's normal if screen is bright. Especially if carrier bloat is still there. Post screens, all you have, and what carrier. The phone could have been sick in a search state.
I don't think my phone is tied to any carrier, it was bought from just a regular electronics shop, but frankly I did a facory reset and didn't realize that all my screenshots will be gone too. Do you really think it's normal that 10 hrs of idling causes 15% battery loss? And it has the stock LG apps (safety care, life square, cell broadcast etc.). What do you mean by "The phone could have been sick in a search state."? My screen brightness is on 70%.
It's normal with bloat in it. They all have bloat stock. 70 is high and can eat at the battery pretty good. I mean it could have software glitched and was struck searching for activation behind the scenes. Use Wake Lock Detector and see what is keeping it awake.
This, almost 20% drop was caused by downloading 3 apps (facebook, facebook messenger and twitter), updating ~10 apps (all done via wi-fi) and rearranging my home screen.
Steamer86, are you sure? My friend told me that he has been 36 hrs on one charge without changing any settings and just downloading apps, playing games and testing the phone.
Your idle is great at that point in time. Facebook is a battery killer. That's a lot of activity with 70% brightness all the time. It's 17% and medium higher side usage and an hour+ of screen time. What are you expecting? At this rate with 70% constant screen and Wi-Fi pushing pretty good you would get almost 6 hours OST. That isn't bad bud.

I hope you are right, but for helping and giving advice I'm going to hit that 'thanks' button
This night i lost 18% of my battery and my phone was almost all the time on deep sleep.
But i did notice something weird, battery usage shows that Android OS is using up most of my battery and when I press on it and then hit the back button then the Android OS changes to something called surfaceflinger for a millisecond (check the screenshots)

Can you try putting your phone in airplane mode and then turn on Wi-Fi? If you aren't using a cell carrier than there's no need to keep that on.
See how this works in increasing battery life for you.

What runs under "Phone Idle" on the V20. It's been the largest battery consumer for the last week of use that I've noticed. My wife's V20 is the same and I had my brother check his and his wife's V20.
I'm only asking because I'm not see great battery life like other have been reporting. I don't have live wallpaper, have only two widgets on the home screen. GPS is set to battery save, screen is set to auto but that doesn't even come close to chewing up the battery.
Sadly I feel like I'm still using my old 2.5 year G3 where it'll need a charge mid way through the day.

Really??
Pretty sad that needs to be done on a week old phone with minimal apps. I'm not even a heavy user.
I feel like I'm back on my old DroidX days where everything was a factory reset but never helped...

I agree with you. Although my phone is just beyond a week old and does have all my apps installed, a factory reset can't be the solution here. This is the typical "I don't know how to fix this" answer always given by manufacturers and carriers.

In the roughly 3 weeks I've had my V20 I've only seen this once where phone idle was higher than Screen. I started looking thru all running apps for 'keep awake' time being high and noticed Android OS had keep awake of over 2 hours when it's normally less than an hour after a full day use. I power cycled the phone and it stopped.
The weird thing was Android OS didn't show high battery usage even though something was triggering keep awake. Looks like the keep awake was causing phone idle to be high.
I'd look at everything in your battery usage to see if you have any high keep awake times.

Sorry did not mean to be short in my response. When you set up your phone did you restore it from another phone using the nfc bump thing? I did the same and my phone battery was the same way. Wouldn't last even half a day. After i factory reset and set everything up manually i get 18+ hrs with 7 hrs screen on time sometimes.
If this situation doesn't apply to you then maybe a reset won't help. But you have to understand your situation isn't normal.
Make sure Google now features are all turned off and not running in the background.

I'll have to go through the apps one by one like I did previously on my G3 and see. Now within the battery stats there is only a handful of apps like hangout, play music, chrome and camera. The rest is OS related so that's why I was curious what ran under Phone Idle.

No and sadly I was looking for that feature a week ago but couldn't find it so I had to individually install most of my apps I had on my previous phone...made for a long night along with the additional emails and configuration or icons and such.
I'll keep digging away at the phone...I really want to like this phone ?
Has there been a definitive resolution to "phone idle" battery drain? I just got a V20 2 weeks ago on sale for $360 and its a fantastic upgrade over the One+1 I've been rockin all these years, but I'm also suffering from mediocre life due to whatever phone idle is. Some forums (for other phones) say phone idle is related to your wireless signal. I'm still with the same carrier and frequenting the same locations and had no such battery drain with that old One+.
i finally discovered whats was goin on with me..
i had the same issue..
phone idle was topping my battery usage list
it turns google plays have this "locationmanager service " and locationwhatever" that kills your battery over wifi even with location button off
Go to locations/ 3 dots in top right corner/ turn off WiFi scan. See if that helps.
My phone has been suffering from poor battery life for quite some time now, here are the screenshots, Android OS has been this high on almost all battery cycles.
I disabled wifi scanning as suggested above and will watch the performance, does the community have any other inputs to fix this? View attachment 4212978View attachment 4212979

Phone idle is always the biggest battery draw on my phone too. I have minimal apps too. No Facebook or similar types of apps. I'm on a Verizon V20 stock with the latest security update. Is this normal V20 behavior to have phone idle consume more battery than everything else?
how about doze mode , isnt that meant to help with this sort of problem ? ( my phone is currently on a ship )
Any update. İ have the same problem

So what did you do?
Would also be grateful if anyone shared a solution.
I specifically have a SIM-unlocked Sprint model (LS997) which am using in Europe with another carrier.
Using it in LTE preferred mode drains about 10-15% overnight.
Using it in WCDMA preferred mode drains up to 5% per night (yes, wifi and cellular data OFF and many apps greenified) . So I'm really interested in how this can be fixed and achieve 0% battery drain across several hours.
Or maybe it's SIM-unlocked Sprint ROM related?? I can't root my phone since it has the Feb 2017 patch and is a ZV6.
I suspect rooting it and using another ROM would solve this + the annoying issue of not being able to send images via FB Messenger and Viber while on cellular data (I imagine the Sprint guys placed some kind of restriction to deny media transfer for these apps when using cellular data).
I have noticed this too.. wondered why "phone idle" takes most battery... any suggestions would be great!
I am also curious about the solution. Phone Idle is at top. Even without SIM card. 30% drains during a night (everything is disabled, but no airplane mode is on). I tried factory reset, reinstall older ROM, replace battery, use no app but still sucks.
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.
